1Block is a digital fashion NFT marketplace that was jointly developed with CryptoGames Inc., which develops blockchain games and NFT services.

1) Auctionable using WETH (Wrapped ETH)

NFTs can be auctioned in the NFT marketplace 1Block Shop; bidding is using WETH (Wrapped ETH). Auctions enable NFTs to be offered at a fair price and for new demand to be created by catching the attention of greater numbers of people. In addition to auctions, fixed-price sales are also possible.

2) NFTs can be purchased easily using a credit card

To support a safe and secure purchasing experience, the team has introduced a payment platform that is used in over 120 countries and by millions of companies around the world. Payment for NFTs can be settled immediately, without having to prepare crypto-assets in advance, so the buying experience is the same as that of shopping on an EC site.

3) Log in using social media

Users can log in via social media such as Google, LINE, Twitter, Discord, etc., and the platform is easy to use, even by people who have never owned an NFT before. URL:
